Specification of Letters Patent.

Patented Jan. 9, 190e.

To all whom it may concern:

Be it known that I, MYRON CossEY, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city and State of N ewYork, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification.

My invention relates to means for hanging laterally-moving doors.

I will describe a structure embodying my invention and then point out the novel features in claims.

In the'accompanying drawings, Figure l isa view, partly in side elevation and partly in vertical cross-section, of a construction showing a laterally-movable door and ernbodying my invention. Fig. 2 is a cross-section view of the construction shown in Fig. 1 and taken on the line as of Fig. l. Fig. 3 is a detail perspective view of one form of carrier for antifriction devices, and Fig. 4 a similar view of a slightly-modified form. Fig. 5 is a view in side elevation,.illustrating modifications of my invention; and Fig. 6 is a detail cross-section view taken on the line y y of Fig. 5.

In the drawings similar letters and figures of reference designate corresponding parts,

I will premise that in this class of devices where the part from which the door is suspended travels on antifriction devices it is important that the antifriction devices while left perfectly free to roll or travel along their tracks or supports should be kept in proper relative positions, or should the antifriction devices be arranged in sets the sets should be kept in proper relative positions. I/Vhere this is accomplished, a much better support is obtained for the door at all points of its travel. It is also important that the antifriction devices or sets of devices should be in position to support the door at the end of each full lateral movement of the door.

Referring to the drawings, 1 designates la suitable base-plate, and 2 3 4 bars or rails extending longitudinally of the base-plate 1. They may be of any proportions in eross-sec tion and of any lengths. The bars 2 and 3 constitute one element and Vbar 4 another ele ment, and one of these elements is adapted to have movement with respect to the otherthat is to say, the bars 2 3 maybe fixed against movement and the bar 4 may have movement between and along the bars 2 3, or the bar 4 may be fixed against movement andthe bars 2 and 3 have movement along the bar 4. either case the door is suspended from the movable bar or bars. In any case the movable bar or bars may be termed a carriage and the fixed bar or bars a track In the preferred form of my invention the bars 2 and 3 are fixed to the base-plate l and constitute the tracks, while the bar 4 is movable between and along the bars 2 3 and constitutes the carriage. I shall for convenience hereinafter refer to the bars 2 3 as the tracks and the bar 4 as the carriage.

D designates a door, which is suspended by suitable hangers I-I from the carriage 4.

The carriage 4 and the tracks 2 and 3 are provided along their adjacent edges with grooves substantially circular in cross-section for receiving antifriction devices, which, as here shown, are in the form of balls.

The antifriction devices between the car riage 4 and the tracks constitute what may be termed a set, or in the case of at least four antifriction devices arranged in pairs and one antifriction device in each pair being arranged above the other anti'friction device of the same pair each pair of antifriction den vices may constitute a set. In order that the antifriction devices may be kept in their relative positions, I provide suitable carriers. These carriers comprise strips having openings for the antifriction devices and means by which the carriers are all connected together in order that all the antifriction devices may be relatively spaced apart. There may be any number of carriers, which may be connected in any desired manner. In any case there should be at least four antifrietion devices, as I have found by'experience that at least this number is necessary to accom-V plish the results desired, which I have ale ready set forth immediately following my de scription of the drawings. In the construction where only four balls are used they willY be arranged two in each set.

Referring now to Figs. l, 2, and 3, the carriers preferably comprise two vertically-arranged strips or pieces 5, each provided with two openings 5a, and a longitudinally-extending strip 6, which is suitably joined to the two strips 5, or the strip 6 may be integral withthe two strips 5. The strip 6 serves to IOO IOS

connect the carriers and to relatively space them, and therefore the antifriction devices. All antifriction device 9 is placed in each opening 5a.V The carriers 5 in this form are ranged one above the other. Referring now to Fig. 4, the carriers are so arranged as not to have the antifriction devices opposite to each other, as in Fig. 3. Referring now to bigs'in'd 6, the carriers for the sets of antifriction devices are independent of each other, and each carrier consists of a strip 6a, provided with suitable openings. It will be seen that upon a movement of the door D laterally in either direction the antifriction devices on both sides of the carriage will move to support the carriage in any position to which it may be moved between the two tracks, and by reason of the spacing of the antifriction devices relatively to each other and maintaining this spacing at all times a uniform support for the carriage is always provided.

Should the 'antifriction devices be prevented from moving with the carriage-as, for example, by their sticking in the grooves in the tracks-so that the carriage will have a movement relatively to the held antifriction devices, I provide means for causing the antifriction devices to be moved by the carriage 4 upon a full lateral movement of the door in either direction. As shown, this may be accomplished by providing pins or studs 8 at the ends of the carriage 4, which engage with the carrier to cause it to move with the carriage. In the forms of carriers in which the cages are joined only one pin or stud 8 is necessary at each end of the carriage. These pins or studs 8 act in connection with the stops 10 to always have the antifriction devices in the position which will afford the best support for the door. In practice the proper position for the antifriction devices is dependent mainly upon the door and is determined in part by the position of the carriage to the tracks when the door is in an eX- treme position. After this proper position has been determined in each case the pins 8 and stops 10 may be so arranged that the antifriction devices will be moved by them in case the antifriction devices should not always move with the carriage to their proper position.

In the accompanying drawings I have shown the door hanging by hangers from the intermediate bar or track and the intermediate bar or track being movable between the outside bars, which are fixed. It will depend, however, upon the precise structural details of the building or other structure as to how the various parts comprising my invention shall be attached to the door. For example, the intermediate bar might be fixed and immovable and secured to a iixed portion of the structure. In this case the outside bars, which might be formed of either one or two pieces, would be secured to the door.

What I claim as new, and desire to secure by Letters Patent, is

l. In a door-hanger the combination with two outside bars and an intermediate bar, one of said elements being movable with respect to the other, of a plurality of movable antifriction devices on each side of the intermediate bar and between it and the outside bars, and means for retaining a plurality of antifriction devices on one side of the intermediate bar in position relatively to a plus rality of antifriction devices on the other side thereof.
